Abstract

Una mecha o espoleta (cartucho) con energía mínima, que comprende un tubode plástico con un canal, el canal contiene un material reactivo capaz,mediante detonación o ignición, de sostener una onda de choque dentro delcanal, el tubo comprende por lo menos dos capas de materiales plásticos,una primera capa plástica más cercana al canal, y una segunda capaplástica fuera de la primera capa, por lo menos la segunda capa contieneuna cantidad principal de resina de polímero orientable por tracción oarrastre. El polímero en la segunda capa es orientado axialmente a ungrado de orientación (como se define) de más de 25% y menos de 95%, y elpolímero de la primera capa tiene un grado de orientación axial que noexcede al 10% de unidades de grado de orientación más que la segunda capa.El tubo se puede fabricar por a) formación, por extrusión de la primeracapa de plástico, la primera capa en forma de tubo, b) introducir elmaterial reactivo en el canal del tubo, c) limitar la tensión oestiramiento de la primera capa para proporcionar un grado bajo deorientación, que no exceda al 10% (como se define), d) formar porextrusión de la segunda capa plástica, la segunda capa alrededor delprimer tubo, mientras que la primera capa tiene el grado bajo deorientación, y e) estiramiento en frío de la primera y segunda capasjuntas.A wick or fuze (cartridge) with minimal energy, comprising a plastic tube with a channel, the channel contains a reactive material capable, by detonation or ignition, of sustaining a shock wave within the channel, the tube comprises at least two layers of plastic materials, a first plastic layer closest to the channel, and a second plastic layer outside of the first layer, at least the second layer contains a major amount of tensile or drag orientable polymer resin. The polymer in the second layer is axially oriented to a degree of orientation (as defined) of more than 25% and less than 95%, and the polymer of the first layer has a degree of axial orientation that does not exceed 10% of degree units orientation more than the second layer.The tube can be manufactured by a) forming, by extruding the first layer of plastic, the first tube-shaped layer, b) introducing the reactive material into the tube channel, c) limiting the tension or stretching of the first layer to provide a low degree of orientation, not exceeding 10% (as defined), d) extrusion of the second plastic layer, the second layer around the first tube, while the first layer has a low degree orientation, and e) cold stretching of the first and second joint layers.
